Engine Speed vs Vehicle Speed for 6MT

[StormTrooper]

As long as you shift out of first after 6500 you'll be out of the torque dip in second.... From what I've seen this graph is accurate.

Driving it around at 4500ft at about 60°F it seems alright. Never really has a punch or comes alive but it isn't slow.

You're assuming the redline of the car is 8k rpms like the graph shows. Redline is 7400, which in second gear is just shy of 60mph.

But if you want to hit 60 at the top of second, get a tune with a raised limiter.

Here's a different take to avoid the torque dip that I found while the engine was under break-in (and haven't used since).

At about 15 mph shift to 2nd.
At about 30 mph shift to 3rd.
At about 40 mph shift to 4th.
At about 50 mph shift to 5th.
At about 60 mph shift to 6th.

I doubt that it was planned this way, but I thought is was a bit amusing while I was trying to keep the revs under 4000. The charts confirm that this is a possible path through the gears on our cars.

6AT will hit 60 in 2nd. Actually 63 if you pull it all the way to limiter.

But still shows slower 0-60 times than the MT

I think it has to do with the launch. on AT you can only launch about 2-2.5k and it has a bog as you pull through torque dip. where as MT you can launch and not be through the dip further. not a big deal to me as i don't really care about straight line speed. just an observation i have noticed at the limit.

That's true ! Yeah it's not like I'm mocking the at but the torque dip destroys it with its launch

This is probably one of the more informative threads here...

Interesting graph. Thanks
